Trail making test performance in Vietnam combat veterans with and without posttraumatic stress disorder.

The present study investigated variables associated with performance on the Trail Making Test from the Halstead-Reitan neuropsychological test battery in Vietnam combat veterans. There was a significant difference in performance between veterans with and without PTSD on both parts of the Trail Making Test. In subgroup analyses excluding participants on medications (antianxiety, antidepressant, and cardiac), comorbid diagnoses (history of alcohol or substance abuse, history of major depression and comorbid anxiety disorder) and compensation-seeking status, the group difference on Trails B remained significant. However, subgroup analyses suggested that poorer performance on Trails A was influenced by antianxiety and cardiac medications, as well as heavy combat exposure status.

Chronic posttraumatic stress disorder and chronic pain in Vietnam combat veterans.

A study was conducted to investigate chronic pain patterns in Vietnam veterans with posttraumatic stress disorder (PTSD). Combat veterans with PTSD completed standardized PTSD severity, pain, somatization, and depression measures. Of 129 consecutive out-patient combat veterans with PTSD, 80% reported chronic pain. In descending order were limb pain (83%), back pain (77%), torso pain (50%), and headache pain (32%). Compared to PTSD combat veterans without chronic pain, PTSD veterans who reported chronic pain reported significantly higher somatization as measured by the Minnesota Multiphasic Inventory 2 hypochondriasis and hysteria subscales. In the sample of 103 combat veterans with PTSD and chronic pain, MMPI 2 hypochondriasis scores and B PTSD symptoms (reexperiencing symptoms) were significantly related to pain disability, overall pain index, and current pain level MMPI 2 hypochondriasis and depression scores were also significantly related to percent body pain. These results are discussed in the context of current conceptualizations of PTSD.

Prevalence and correlates of heavy smoking in Vietnam veterans with chronic posttraumatic stress disorder.

A study was conducted to investigate smoking patterns in 445 Vietnam veterans with and without posttraumatic stress disorder (PTSD). Combat veterans with PTSD reported similar occurrence of smoking (53%) compared to combat veterans without PTSD (45%). For those who smoked, combat veterans with PTSD reported a significantly higher rate of heavy smoking (> or = 25 cigarettes daily): 28% of combat veterans without PTSD were heavy smokers and 48% of combat veterans with PTSD were heavy smokers. PTSD diagnosis and heavy smoking status were independently and differentially related to motives for smoking. In combat veterans with PTSD, heavy smoking status was positively related to total health complaints, lifetime health complaints, health complaints in the past year, negative health behaviors, total PTSD symptoms, DSM-IV C cluster (avoidance and numbing) and D cluster (hyperarousal) PTSD symptoms. Heavy smoking status was also associated with fewer positive health behaviors.
